Directions

1. Soften the onion, chiles and tomato. Heat a saucepan over medium heat, melt the butter, add the onion and chiles, and cook until the onion just begins to soften, about 3 minutes. Add the tomato and cook for 2 more minutes.

2. Make and thicken the sauce. Add the remaining ingredients except the cheese, bring to a boil, and simmer, stirring often, until the mixture has thickened to the consistency of a thick cream soup, 5 – 10 minutes.

3. Add the cheese. Add the cheese, remove the saucepan from the burner, and stir until the cheese is melted.
